Graphics Problem following migration to a RAID set up

I need some advice/help please on a problem which I cannot solve.

I hope it's an easy one to solve, but being a total n00b on OSX I have run out of steam.

Quick summary of progress:

Rig:
Gigabyte GA-EP45UD3R
Q6700 CPU O/C to 3.6 GHz (stable)
XFX GTX260 816MB 216 Cores
4 x 500GB drives (was in W7 Intel Raid config)
1 x 1TB Drive under Intel raid but no raid.
1 x 40Gb ATA Drive managed as ACHI via Bios (Installed 10.6.3 to)

1. Followed instructions in here and installed 10.6.3 to a single drive.
2. Reinstalled memory to 8Gb and PCi cards and windows drives, reconnected 2nd monitor.
3. Booted fine but problem with only 1280x800 resolution
4. Found Nvidia injector, ran it and installed latest Nvidia drivers.
5. Reboot : Success. Dual Monitors running a treat and all stable. Sound working. Network work. All is good.
6. Old 40Gb drive was slow, so decided to follow well publicised instructions to implement OSX software RAID on my 4 x 500GB drives (which maxed out the PCI bus with W7 @ 500MB/s read)

7. OSX SL booted of the new Raid configuration fine (whoa whoa), but the graphics driver has reverted back to the 1280 x 800 and no option to change.
8. If I boot using the original 40GB drive, the screens are fine. So I know the system on there is 100%.
9. I tried to reinstall the Nvidia Injector and Drivers, but the drivers stated all was up to date and didn't need it, so it aborted. Reboot and still the problem.
10. Reboot using iBoot and selecting the Raid disk. Blow me, both monitors are working at full resolution. So shutdown and reboot to see if it had sorted itself. But no, same problem.
11. Boot iBoot, into Raid boot up and rerun OSX 10.6.6 combo update. Re-ran MultiBeast as previously selecting all the right options for my kit (as I did before). Installed to the RAID disk. Reboot. Same problem.

So, I know I have a working configuration on my 1 x 40Gb drive. How do I get my RAID system in the same shape?

Thanks for your patience.

[SOLVED]

Believe it or not, but the Guides to set up RAID as shown here:

All more or less get it right, but I could not get any to boot up.

When I find some time I'll write my own procedure for others to follow. It's only taken two and a bit full days of me learning about Hackintosh's! I've never used a MAc before let alone get under the "hood".

I now have 4 x Seagate ST3500418AS in RAID 0.

Attached are the Xbench files for the single drive and for the 4 x drives.

Overall Result:-

Single Drive: 81.29
4 x Drives RAID 0 : 224.89

Result!

Just need to put back in my other 4GB Ram and hook it all back up! It should fly with 8GB.
